原发性肝癌是我国常见的恶性肿瘤之一,对于早期病变,手术治疗是其首选的治疗方式。但是大多数的肝细胞肝癌患者就诊时已失去手术切除机会,其中,门脉或下腔静脉癌栓是肝癌患者失去手术机会的主要原因之一。肝细胞肝癌伴门脉癌栓(portal vein tumor thrombosis, PVTT)患者,其致死的原因除了肝功能衰竭外,癌栓引起的腹水、食管静脉曲张破裂出血也不少见。对门脉或下腔静脉癌栓患者进行手术取栓颇为艰难,如果门脉主
Primary liver cancer is one of the most common malignancies in China. For early lesions, surgical treatment is its preferred treatment.
